Note: Components in different batches of kits are not interchangeable.

Storage conditions and shelf life

Store and transport at room temperature. The shelf life is 24 months.

Applicable instruments

Instruments and equipment during sample processing, such as pipettes, vortex mixers, water baths, etc.

Sample requirements

Precision

When this kit is used for extraction from the in-house precision reference CV for 10 replicates, the coefficient of variation (CV, %) of Ct value is not more than 10%.

Inter-batch difference

When the in-house precision reference is tested on three batches of kits under trial production upon repeated extraction and, the coefficient of variation (CV, %) of Ct value is not more than 10%.

Performance comparison

● Extraction efficiency comparsion

200	35.25	35.9	35.83	35.96
100	36.99	37.7	38.13	undet

The extraction efficiency of sample releaser was similar to that of magnetic beads method, and the concentration of pathogen could be 200Copies/mL. ● CV value comparison
